A .NET client SDK for MediaKind MK.IO

This project is an open source .NET SDK for MediaKind MK.IO. For maximum compatibility, it targets .NET 8.0, .NET Standard 2.0 and .NET Framework 4.6.2.

Link to MK.IO Nuget package.

Usage (C#, .NET)

MK.IO Personal API Token

You need to use the new MK.IO Personal Access Tokens to connect to the API. This is a Json Web Token (JWT) also called Personal API Token. You can create them in the MK.IO portal and revoke them if needed.

To create one :

1. Open a web browser and log into https://app.mk.io (sign in with Microsoft SSO).
2. Once you are logged in, click on your email in the drop-down menu in the top right corner. More details here.

For more information, please read this article.

This SDK also brings token management features for the MK.IO API. You can use the SDK to create, list, revoke, and get details of your personal API tokens, using client.Management.YourProfile.

End-to-end sample code

Video encoding and publishing

There is a documented end-to-end sample code available in the SampleNet8.0 project, in file SimpleEncodingAndPublishing.cs.

This sample code does the following :

• upload a mp4 file to a new asset using authentication in the browser (you need contribution role on the storage)
• create the output asset
• create/update an encoding transform
• submit an encoding job
• create a streaming locator for the encoded asset
• create and start a streaming endpoint if there is none
• list the streaming urls and test player urls.
• clean the created resources if the user accepts

Run the SampleNet8.0 project to execute this sample code.

Advanced video encoding and publishing

There is a documented end-to-end sample code available in the SampleNet8.0 project, in file AdvancedEncodingAndPublishing.cs.

This sample code does the following :

• upload a mp4 file to a new asset using authentication in the browser (you need contribution role on the storage)
• create the output encoded asset
• create/update an encoding transform
• submit an encoding job
• create/update a transform to do the transcription of the video using AI
• submit a job to generate the transcription (vtt)
• create/update a transform to insert the vtt as a text track
• submit a job to insert the vtt as a text track in the encoded asset
• create/update a transform for thumbnails
• submit a job to generate a thumbnails sprite
• create a download locator for the thumbnails sprite and thumbnails vtt and list the Urls
• create a streaming locator for the encoded asset
• create and start a streaming endpoint if there is none
• list the streaming urls and test player urls (within the Bitmovin player, go to the settings and enable subtitles to English).
• clean the created resources if the user accepts

Edit Program.cs file in SampleNet8.0 to uncomment the line await AdvancedEncodingAndPublishing.RunAsync();, comment await SimpleEncodingAndPublishing.RunAsync();, and run the SampleNet8.0 project.

Live streaming

There is a documented end-to-end sample code for live streaming, in file SimpleLiveStreaming.cs.

What the sample does :

• create a live event (with an option to enable live transcription)
• create a live output asset
• create a live output
• create a locator
• create and start a streaming endpoint if there is none
• list the streaming urls and test player urls.
• propose to the user to convert the live asset to a mp4 asset and create a download locator to download the mp4 file(s)
• clean the created resources if the user accepts

Edit Program.cs file in SampleNet8.0 to uncomment the line await SimpleLiveStreaming.RunAsync();, comment await SimpleEncodingAndPublishing.RunAsync();, and run the SampleNet8.0 project.

Other examples

Here is an example on how to use the SDK to manage assets and streaming endpoints :

using MK.IO;
using MK.IO.Models;

// **********************
// MK.IO Client creation
// **********************

var client = new MKIOClient("yourMKIOSubscriptionName", "yourMKIOPersonalAPIToken");

// get user profile info
var profile = client.Account.Management.YourProfile.GetProfile();

// Get subscription stats
var stats = client.Account.GetSubscriptionStats();

// Get monthly usage of MK.IO subscription
var monthlyUsage = client.Account.GetSubscriptionUsage();

// *****************
// asset operations
// *****************

// list assets
var mkioAssets = client.Assets.List();

// list assets with pages, 10 assets per page, sorted by creation date
var mkioAssetsResult = client.Assets.ListAsPage("properties/created desc", null, null, null, 10);
while (true)
{
    // do stuff here using mkioAssetsResult.Results

    if (mkioAssetsResult.NextPageLink == null) break;
    mkioAssetsResult = client.Assets.ListAsPageNext(mkioAssetsResult.NextPageLink);
}

// get asset
var mkasset = client.Assets.Get("myassetname");

// create a first asset, letting MK.IO generates a container name
var newAssetName = MKIOClient.GenerateUniqueName("asset");
var newasset = client.Assets.CreateOrUpdate(newAssetName, null, "storagename", "description of my asset");

// create another asset and use labels to tag it. Container name will be the nae of the asset
var newAssetName2 = MKIOClient.GenerateUniqueName("asset");
var newasset2 = client.Assets.CreateOrUpdate(
    newAssetName,
    newAssetName, // container name
    "storagename",
    "description of asset using labels",
    AssetContainerDeletionPolicyType.Retain,
    null,
    new Dictionary<string, string>() { { "typeAsset", "source" } }
    );

// list assets using labels filtering
var sourceEncodedAssets = client.Assets.List(label: new List<string> { "typeAsset=source" });

// delete created asset
client.Assets.Delete(newsasset.Name);

// get streaming locators for asset
var locatorsAsset = client.Assets.ListStreamingLocators("asset-1b510ee166");

// Get tracks and directory of an asset
var tracksAndDir = client.Assets.ListTracksAndDirListing("asset-ef2058b692");


// ******************************
// Streaming endpoint operations
// ******************************

// get streaming endpoint
var mkse = client.StreamingEndpoints.Get("streamingendpoint1");

// list streaming endpoints
var mkses = client.StreamingEndpoints.List();

// create streaming endpoint
var newSe = client.StreamingEndpoints.Create("streamingendpoint2", client.Account.GetSubscriptionLocation()!.Name, new StreamingEndpointProperties
            {
                Description = "my description",
                ScaleUnits = 0,
                CdnEnabled = false,
                Sku = new StreamingEndpointsCurrentSku
                {
                    Name = StreamingEndpointSkuType.Standard
                }
            });

// start, stop, delete streaming endpoint
client.StreamingEndpoints.Start("streamingendpoint1", true);
client.StreamingEndpoints.Stop("streamingendpoint1", true);
client.StreamingEndpoints.Delete("streamingendpoint1");

Additional samples are available :

• storage operations
• transform and job operations
• account filter and asset filter operations
• content key policy and streaming locator operations

Async operations are also supported. For example :

// *****************
// asset operations
// *****************

// Retrieve assets with pages for better performances, sorted by names, with a batch of 10 assets in each page
var mkioAssetsResult = await client.Assets.ListAsPageAsync("name desc", null, null, null, 10);
while (true)
{
    // do stuff here using mkioAssetsResult.Results

    if (mkioAssetsResult.NextPageLink == null) break;
    mkioAssetsResult = await client.Assets.ListAsPageNextAsync(mkioAssetsResult.NextPageLink);
}


// ******************************
// Streaming endpoint operations
// ******************************

// get streaming endpoint
var mkse = await client.StreamingEndpoints.GetAsync("streamingendpoint1");

// list streaming endpoints
var mkses = await client.StreamingEndpoints.ListAsync();

// create streaming endpoint
var location = await client.Account.GetSubscriptionLocationAsync();
var newSe = await client.StreamingEndpoints.CreateAsync("streamingendpoint2", location!.Name, new StreamingEndpointProperties
            {
                Description = "my description",
                ScaleUnits = 0,
                CdnEnabled = false,
                Sku = new StreamingEndpointsCurrentSku
                {
                    Name = StreamingEndpointSkuType.Standard
                }
            });

// start, stop, delete streaming endpoint
await client.StreamingEndpoints.StartAsync("streamingendpoint1", true);
await client.StreamingEndpoints.StopAsync("streamingendpoint1", true);
await client.StreamingEndpoints.DeleteAsync("streamingendpoint2");
